Opinions On Wolff Gunsprings For M1 Tsmg?

I am not having a ton of luck finding new-old-stock WWII era recoil springs for my recently-arrived Bridgeport/Savage M1. Phil Askew said he is out of them, and I'd rather not use SARCO's springs because who knows how many rounds those have fired.

I have an Auto Mag that was inscrutable and after popping a set of Wolff springs in, it was totaly scrutable..... So I can attest to them helping in that gun.... Never had any Thompson spring probs*.....

I would say that getting Wolffs catalog would explain everthing in there. They explain everything about springs and it opened my eyes on the importance of them. "veriable' and 'conventional' springs are explained and "extra Power" in great detail. if you own any other weapons which take springs. This book is indispenceable.-adlake
